I ii W The invention relates to a collapsible post, 1 as described in thepresent specification-and- I illustrated in the-accompanying drawingsthat form partof the same. 1

The invention consistsessentially ofbthe down in order to be out of theway, that is" to say, to'make very certain that the post in its uprightposition will be strongenough to support any goods that may. be piledagainst it, especially so in the use of posts on flat cars in railways,though 'the" same kind of post may be applied in-many directions; toproduce thesepa rticular posts at a reasonable price so that the usethereof will not entail any extra expensein equiprnent; and generally toprovide a reliable durable and efficient post for many uses. Inthedrawings, Figure 1 is a perspective view of the extended post. I

Figured is" a perspective detail of onesec- ,Figure 5 is a fragmentary detail showing theglocking slot. l Like:numerals of reference'indicate cor responding parts .in thevariousvfigures. Referring to the drawings, the main section of'thepost, that is tosay, the ground or post section is indicated by thenumeral 15,

Diametrically opposite this slot 17 and I particularly that part of theslot which is in the wall of the tube, the slot 18, is made, i

' this slot being open at its lower end.

In' the length of the tub lar-member 15,

- the slot 19 is made, this slot is elongated and inner -;length throughthe outer 7 length a Fi ure2 is a perspective view of the post i I ingthe section 15 in its collapsed posltion.

'ceivled insaid slot,a slot in said lug, and a pin ing a slot in onesection, a tubular post 'hav s turned at the upper end toform the. lock---ing ;slot 20,;whi'ch is of- L s'hape atthe end 21 th e'reof. r At theextreme upper end of the member 15, the lugs 22 and 23'project from thesides and-theselugs'are intended for lifting purposes, that is to ,say,tolift thisrlength 15 bodily up to clear the lug 16. a

The angle plate bracket 24 is formed in the section 25 with the slot 26into which the lug 16 extends in the'upright position of the post andthe pin 27 extends through the slots 7' v 17 and 18,-the head 28 of saidpin engaging the outer su'rfaceof the wall of the tube 15 and the innerend of the pin extending through the section29 of the bracket andsecured on the-other side of said section by the nut :30.

The extensible sections 31 and 32 are'teleone Within the section "15,and each have the lifting lugs33, and one of'coursehas the Ilongitudinal slot 24, the same as the slot 19, the'lugs 35 running insaidslots from the n the operation of this post the lower secbleposition are lifted upwardly until the lugv I slot 17, then the pin 27jengages the length 15' ingtheslot 18, thereby- To exten'd the post,that is make it higher, the sections 31 and 32, one or both of them, are

lifte'd so as to bring the lugs 35 into the locking slots atthe ends ofthe elongated slots. I
